Version V1.14 (2022-02-01)

FTP Server

  1. Uploading files into sub folders inside of "All modules" could fail for some FTP clients, because the FTP server responded with "550 No such file or directory" to the "CWD" command. Fixed.

Fail-safe mode

  1. Flasher Hub could not write to files on external USB drives formatted with specific filesystem (e.g. FAT16). Fixed.
  2. Flasher Hub could sometimes fail to detect a connected USB drive, depending on its label. Fixed.

Web interface

  1. Files: Trying to create a folder inside the "All modules" folder always failed. Fixed.
  2. Programming: Project files located inside a subfolder instead of the root folder (e.g. "MyFolder/MyProject.cfg") could not be selected nor programmed. Fixed.
  3. Programming: Opening the page could could take multiple seconds, depending on the number of connected modules and their file structure. Fixed.
  4. Programming: After clicking "Refresh project lists" and before the project lists were updated, "No projects found" was displayed. Changed to "Looking for project files...". Fixed.
  5. Programming: Refreshing the project lists manually by clicking "Refresh project lists" could take multiple seconds, depending on the number of connected modules and their file structure. Fixed.

Version V1.10 (2021-12-08)

Flasher Hub

  1. Fail-safe mode could not be enabled with USB drives using the "FAT32" file system, because the expected label name ("flasherhubrw") was too long. From now on, the label name "flasher" is supported as well.

Log

  1. Implemented Flasher Hub log file rotation: A new log file is created once the current file reaches a certain file size. After a max. number of log files has been stored, the oldest log file is removed when a new log file is created.

User guide

Version V1.08 (2021-11-12)

Flasher Hub

  1. Introduced "fail-safe" mode for Flasher Hub: https://wiki.segger.com/Flasher_Hub#Fail-safe_mode.

TERMINAL

  1. While one operation (e.g. #AUTO 1) was still ongoing, trying to start another operation (e.g. #AUTO 2) in parallel threw an error message "Server is busy". Fixed.
  2. Under some circumstances, the result for a failed operation (e.g. #AUTO 1) would be just "#OK" (without any timestamps or similar). Fixed.
  3. Trying to start an operation (e.g. #AUTO 1) could fail for a module that was temporarily disconnected and reconnected since the last time it was. Fixed.
  4. Starting operations (e.g. #AUTO 1) would take some time (ca. 4 - 5 seconds) after the command was issued and before the operation was started. Fixed.
  5. Starting operations (e.g. #AUTO 1) on modules that were not available did not print any messages to the terminal. Fixed.
  6. After issuing multiple commands that keep modules busy (e.g. #AUTO 1, #AUTO 2), a #DONE would be sent to the client for each finished command, instead of just one #DONE after all issued commands were finished. Fixed.
  7. When executing the #SELECT command to select a project for multiple modules, the execution was slow (it took a few seconds). Fixed.
  8. Improved speed when executing the #SELMODULE command.
  9. Improved speed when executing the #CANCEL command.
  10. Improved speed when executing the #FWVERSIONMOD command.
  11. Improved speed when executing the #SERIALMOD command.
  12. Calling #SELMODULE without specifying any modules caused the module selection to be cleared instead of just returning the current selection. Fixed.
